実験手順

A mixture of methyl 2-methyl-5-morpholino-3H-imidazo[4,5-b]pyridine-7-carboxylate (207 mg, 0.75 mmol), 1-(bromomethyl)-2-methyl-3-(trifluoromethyl)benzene (285 mg, 1.125 mmol) and Na2CO3 (239 mg, 2.25 mmol) in DMF (10 mL) was stirred at 80° C. for 3 h. TLC showed no methyl 2-methyl-5-morpholino-3H-imidazo[4,5-b]pyridine-7-carboxylate left. It was cooled to room temperature and poured into water (50 mL) and filtered. The solid was dissolved with DCM (150 mL) and it was washed with brine (100 mL×3) and the organic layer was dried over anhydrous Na2SO4, filtered and concentrated in vacuo to afford the desired product as a brown solid (320 mg, 95%); LC/MS: MS (ES+) m/e 449 (MH+); 1H NMR (300 MHz, DMSO-d6) δ ppm 2.40 (s, 3H), 2.51 (s, 3H), 3.41 (t, J=4.8 Hz, 4H), 3.68 (t, J=4.8 Hz, 4H), 3.92 (s, 3H), 5.50 (s, 2H), 6.90 (d, J=7.8 Hz, 1H), 7.07 (s, 1H), 7.28 (t, J=7.5 Hz, 1H), 7.62 (d, J=7.8 Hz, 1H).
